SPR1-1737: New mvf_copy.py script #349

Closed ludwigschwardt closed 2 years ago

This makes a local copy of an MVF4 dataset (local or remote). In the process it also allows stripping out correlation products. It currently only supports extracting the autocorrelations via the --corrprods=auto script option. The filtered RDB file and chunks are stored in a new subdirectory (by default "./archive").

The script has much in common with mvf_rechunk.py and might eventually merge with it.

Ready for another pass, @bmerry.
